What is the reason behind the high surface tension of water

Due to the water's polar property, water molecules attract one another. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen cause water to be compressed together. In general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity. The influence of the surrounding environment is due to the adhesive action liquid molecules have at the interface.

It's cell theory. easy name i would think.
